Product Description
Kitmasters 638667 Polyforce Detroit DD Series Tensioner Assembly
Utilizing the PolyForce™ Polymer Torsion Core instead of a spring, this belt tensioner is an instant upgrade from the Gates 38667, the most popular belt tensioner on ’08-’17 Freightliners with DD13, DD15 & DD16 engines.
No Springs Attached
Conventional belt tensioners use springs to hold their position and tension. However, springs can only flex so many times before they fail. PolyForce™ Belt Tensioners replace this spring with a longer lasting, new and unique Polymer Torsion Core. A compressed silicone replaces the spring, thereby eliminating the primary cause of failure.
Improved Bearings
The other common failure point in a belt tensioner is the bearing. The pulley bearing absorbs a huge amount of vibration and can often fail too soon. PolyForce™ Belt Tensioners have dramatically improved pulley bearings to give them extended life. Our bearing is designed specifically for pulley applications and features:
– Outer Ring Rotation
– Anti-Vibration Grease (won’t separate)
